Objectives: To evaluate the long-term safety (primary objective) and efficacy (secondary objective) of antimuscarinic add-on therapy in patients receiving mirabegron.
Methods: During a 2-week screening period, patients (aged ≥20 years, mirabegron treatment for ≥6 weeks, residual overactive bladder symptoms) received mirabegron 50 mg once daily. These patients were subsequently randomized to 52 weeks' treatment with mirabegron 50 mg/day plus an antimuscarinic (solifenacin 5 mg, propiverine 20 mg, imidafenacin 0.
Objectives: To show the efficacy of propiverine hydrochloride in the management of symptoms of stress urinary incontinence in female patients with mixed-type urinary incontinence.
Methods: The study was carried out as a multicenter single-arm clinical trial at 64 institutions in Japan. The participants were female patients aged ≥20 years with mixed-type urinary incontinence.
Objectives: To evaluate the safety and efficacy of tadalafil plus α -blocker combination therapy in Japanese patients with lower urinary tract symptoms suggestive of benign prostatic hyperplasia.
Methods: The present multicenter, randomized, double-blind, placebo-controlled, two-period cross-over study compared the effects of tadalafil and a placebo added to ongoing α -blocker therapy. A total of 171 Japanese patients were randomized.
Purpose: The objective of this multicenter cross-sectional study was to investigate the relationship of nocturnal polyuria in patients with common lifestyle related diseases and overactive bladder, with special attention to hypertension.
Materials And Methods: After baseline assessment, patients recorded 24-hour urinary frequency/volume, blood pressure and heart rate for 3 days. They were stratified into 4 groups based on mean blood pressure, including no hypertension, and controllable, untreated and uncontrolled hypertension, respectively.
The "Japanese Clinical Guideline for Female Lower Urinary Tract Symptoms," published in Japan in November 2013, contains two algorithms (a primary and a specialized treatment algorithm) that are novel worldwide as they cover female lower urinary tract symptoms other than urinary incontinence. For primary treatment, necessary types of evaluation include querying the patient regarding symptoms and medical history, examining physical findings, and performing urinalysis. The types of evaluations that should be performed for select cases include evaluation with symptom/quality of life (QOL) questionnaires, urination records, residual urine measurement, urine cytology, urine culture, serum creatinine measurement, and ultrasonography.

Methods: Patients with OAB symptoms for ≥24 weeks, ≥8 micturitions/24 h on average, and ≥1 episode of urgency and/or urgency incontinence/24 h were randomized to mirabegron (25, 50 or 100 mg) or placebo for 12 weeks. The primary endpoint was change from baseline to end of study in the mean number of micturitions/24 h.
Objective: To investigate pathways involving beta-3 adrenergic receptors (ARs) in detrusor overactivity induced by cold stress, we determined if the beta-3 AR agonist CL316243 could modulate the cold stress-induced detrusor overactivity in normal rats.
Methods: Two days prior to cystometric investigations, the bladders of 10-week-old female Sprague-Dawley rats were cannulated. Cystometric measurements of the unanesthetized, unrestricted rats were taken to estimate baseline values at room temperature (RT, 27 ± 2 °C) for 20 min.

Methods: Normal urinary bladder specimens were obtained from 13 patients undergoing radical cystectomy due to bladder cancer (normal group) and BPH specimens were obtained from 27 benign prostatic obstruction patients receiving transurethral prostatectomy or retropubic prostatectomy. Receptor subtype mRNA expression was determined by real-time reverse transcription polymerase chain reaction on urothelium, detrusor, and whole mucosal preparations.
Objectives: Assess the efficacy and safety of tadalafil 5 mg once-daily in Asian men with lower urinary tract symptoms by pooling data from three clinical studies.
Methods: Data on 1199 Japanese, Korean, and Taiwanese men given tadalafil 5 mg (n = 601) or placebo (n = 598) were pooled from three double-blind, placebo-controlled, 12-week studies. Efficacy measures included International Prostate Symptom Score, and Patient and Clinician Global Impressions of Improvement.
Previously, we reported that implantation of isolated single bone marrow-derived cells into radiation-injured urinary bladders could restore structure and function. However, injections of isolated single cells had some limitations. Thus, in this study, we produced bone marrow-derived cell sheets in temperature-responsive culture dishes that release the monolayer sheets intact.

Patients And Methods: This multicentre, open-label, phase IV study enrolled patients aged ≥20 years with OAB, as determined by an OAB symptom score (OABSS) total of ≥3 points and an OABSS Question 3 score of ≥2 points, who were being treated with solifenacin at a stable dose of 2.5 or 5 mg once daily for at least 4 weeks.
Prostate fibrosarcoma is an extremely rare tumor for which complete excision has been the mainstay of treatment. Although chemotherapy has been attempted in cases with positive surgical margins and/or advanced stage disease, the effectiveness of this therapy has not been established. Herein, we report a case of advanced prostate fibrosarcoma that reacted well to chemotherapy.
